The last time I posted this, I think I worded it poorly and it got misunderstood.

So, I will try and word it more clearly.

While warm air will, normally, create an upward airstream in powdertoy, cold air does not create a downward airstream in powdertoy (Or at least not to my knowledge, maybe the created wind is just too weak.)

So I would love if it was implemented, so you can "pour" cold air into a container and such. would also be nice with CO2 straight out of dry ice cooling down stuff.

Aside from that, I would love to have tools that directly affect ambient heat, which would have the exact same function as the normal cool and heat tools but simply do it with ambient heat.

Combining those tools with a way of setting the ambient temp to your own will (So when you create a winter landscape and someone turns on ambient heat, you do not get immediate spring) would be nice.

I hope I am not asking for too much.
